Tracking shotIn motion picture terminology, a tracking shot (also known as a dolly shot or trucking shot) is a segment in which the camera is mounted on a wheeled platform that is pushed on rails while the picture is being taken. One may dolly in on a stationary subject for emphasis, or dolly out, or dolly beside a moving subject The tracking shot can include smooth movements forward, backward, along the side of the subject, or on a curve. Dollies with hydraulic arms can also smoothly "boom" or "jib" the camera several feet on a vertical axis. Tracking shots, however, cannot include complex pivoting movements, aerial shots or crane shots.Tracking shots are often confused with the long take. A long take is an uninterrupted shot in a film which lasts much longer than the conventional editing pace either of the film itself or of films in general, usually lasting several minutes. It can be used for dramatic and narrative effect if done properly, and in moving shots is often accomplished through the use of a dolly or Steadicam.
